And while it doesn't appear that Apple plans to slow down any in 2009 -- despite the seemingly endless supply of rumors about the health of CEO Steve Jobs -- it's worth reflecting on some of the most notable innovations from Apple in a year that easily ranks as one of the most significant in its 31-year-history.

At last, the iPhone 3G

Without a doubt, the iPhone 3G was in years -- if not the biggest in the company's history. Although the original iPhone had been on the market for a year, the launch of the iPhone 3G in July offered more than a simple upgrade to the handset.

In addition to new features like 3G network support and GPS capabilities, the iPhone 3G launch also bundled in a major update to the iPhone's operating system. Thousands of applications from independent developers soon followed, turning the iPhone from a way-cool phone/PDA into a device that offered an amazing breadth of features.

In particular, it seemed as if the iPhone 3G was aimed squarely at business and enterprise environments -- even if Apple did little to advance that case. The iPhone 2.0 software update, for the first time, allowed businesses to enable push notification of e-mails, contacts and calendar items . It also allowed Exchange security policies to be enforced and all data on a lost or stolen phone to be remotely wiped. And Apple that let IT departments preconfigure settings, including security policies and digital certificates for secure network connectivity, on one or more iPhones before rolling them out to employees.
